** This bug is no longer a duplicate of bug 262066 CPU throttled to 12% with kernel 2.6.27
** Description changed: In 2.6.27-rc9 I noticed a fix/blacklist (commit e84956f92a846246b09b34f2a728329c386d250f) for two ATI laptop that set thermal trip points to insanely low values. I am using current Ubuntu LiveCD which ships kernel 2.6.27-6.9 and I noticed a similar problem on my HP Compaq 6715s (with latest BIOS F.0D 08/20/2008). Steps to reproduce: run current LiveCD (downloaded from http://cdimage.ubuntu.com/daily-live/). The system is really slow, the fan is always active, but ouput fresh air. If can be useful, running the following command as found here: http://marc.info/?l=linux-acpi&m=121396447214047&w=4 I get: $ cat /proc/acpi/thermal_zone/TZ*/trip_points critical (S5): 105 C passive: 16 C: tc1=1 tc2=2 tsp=100 devices=C000 C001 active[0]: 16 C: devices=C39B active[1]: 16 C: devices=C39C active[2]: 16 C: devices=C39D active[3]: 16 C: devices=C39E Maybe it should blacklisted also this hardware? + Apparently the patch is available at + http://bugzilla.kernel.org/show_bug.cgi?id=11516#c52 + See also http://bugzilla.kernel.org/show_bug.cgi?id=11719 Thanks -- [intrepid] HP Compaq 6715s very slow - need to be blacklisted? https://bugs.launchpad.net/bugs/280202 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
